Diagram showing a timeline of Church history

"A group of young Catholic men came to my Kalyvi [monastic hut—Webmaster]. They were very eager and interested to learn more about Orthodoxy. 'Please tell us something that will help us spiritually,' they said. 'Look,' I replied, 'go and take a look at Church History and you will see how in the past we were united and then you took your own way and ended up where you are. Do this and you will be helped. When you are done, come back and we'll have plenty to talk about."

—Elder Paisios the Athonite (+1994), from With Pain and Love for Contemporary Man, p. 384.

The Acts and Decrees of the Synod of Jerusalem, a Synod held in 1672 concerning a work entitled The Eastern Confession of the Christian Faith, which attempted to express Orthodox beliefs in Protestant terms, specifically Calvinism. It was allegedly written by the former Patriarch of Constantinople, Cyril (Loukaris). The "Confession of Dositheos" starts at the bottom of p. 110, and remains an excellent expression of Orthodox theology vis-à-vis Calvinism. Protopresbyter James Thornton offers further historical insights in this excerpt from his book The Oecumenical Synods of the Orthodox Church.

Recommended Books

The Law of God, compiled by Archpriest Seraphim Slobodskoy. This text has become a twentieth-century classic, serving as the chief catechetical text in most Russian Orthodox parishes. It provides basic instruction in all essential matters of the Orthodox Faith, as well as commentary on all key passages of the Old and New Testaments.

Orthodox Dogmatic Theology by Fr. Michael Pomazansky. It is indispensable. For a highly favourable and scholarly review of this exceptional work see The Greek Orthodox Theological Review, 32, 1-2, 1986.

The Roman West and the Byzantine East, by Archbishop Chrysostomos and Bishop Auxentios. This is a superb, short treatment of general differences between East and West. "This little book takes us back to the quest for truth and tells us why we Orthodox believe that our Church is true to the Church established by the Apostles, why she has historical and spiritual primacy. It does so by pointing out differences and by the bold proclamation of Orthodoxy's uniqueness." [from the back cover]. Also, I cannot resist including this excerpt from p. 10: "All history, one might say, is artificial... The Western view of the Christian past, however, is particularly artificial—it is a rather a "whopping lie," as the modern idiom would have it, if only because it ignores the historical experience of more than half of the Christian world, the Christian East, from which Western Christianity itself derives! Yet, it has gained such ascendancy that one is hesitant to challenge it. It is so ubiquitous that even Eastern Christians, especially those living in the West, often embrace it themselves. And if they do not, in fact, embrace it as their personal view, they often feel compelled to speak within its framework in trying to present their own perspectives on the Christian past. The Western view has, indeed, become triumphant, despite its inadequacies in accounting, as we shall see, for a vast part of Christian history."

The Oecumenical Synods of the Orthodox Church, by Protopresbyter James Thornton. “[...T]he Œcumenical Synods[...]occupy a place of paramount importance in the Orthodox Church. [...]Held between 325 and 787, they were summoned by the ruling Roman (Byzantine) Emperors to defend the Church when the fundamentals of Christian belief and teaching came seriously under threat. It often happened that certain heresies, all involving directly or indirectly the Person of Jesus Christ, loomed so large in the Christian world that they required a decisive response on a scale that encompassed the whole of Christendom, one that made crystal-clear to everyone precisely where the True Church of Christ stood and why She stood there. The dogmatic theology that derives from Œcumenical Synods[...]has ‘direct consequences for man’s salvation’ because each system of belief dictates its own unique way of life. [...]Thus, the debates about theology that seem (for example, to some secular historians) as quibbling over minor or abstruse questions were not quibbling at all, and the questions were neither minor nor abstruse. The debates involved issues of life versus death.”
